One of the difficult parts of Orthodox singing will be singing
these melodies from text (usually at best pointed) on a printed page
I can't think of any way around having to memorize all of these tunes.
An easy way to learn them is to sing one or two psalms a day in
the
tone of the week to the appropriate stichera melody for a while. At the
bottom is S.
Rolando's
chant guide.
